UFC 156 Drug Test Results: All Fighters Pass, Overeem Results Not Yet Back | UFC NEWS
Nevada State Athletic Commission official, Keith Kizer, told BloodyElbow.com last night that all fighters from this month’s UFC 156. Rumors had been circulating that one fighter may have failed, but Kizer explained that all the results have been confirmed; the only pending result is the additional blood test conducted on Alistair Overeem. This supplementary test will check his testosterone levels, among other things. Kizer said he expects the results to come back some time next week.
This extra test comes as little surprise, as Overeem tested positive for elevated testosterone levels last year resulting in his removal from a title fight against then champion, Junior Dos Santos, as well as a suspension from competition. Many fans, and even Mirko Cro Cop, credit Overeem’s KO loss to Antonio “Big Foot” Silva at UFC 156 to the termination of his use of performance enhancing supplements.
BloodyElbow.com also reported that the additional test conducted is not a Carbon Isotope Ratio test. Such a test determines if the testosterone in the drawn blood is natural or synthetic. It is among the rigorous tests used by the World Anti-Doping Agency for international competitions.
